Infrastructure-as-a-Service (IaaS) represents a new consumption model for the use of IT resources. An IaaS provider offers customers bandwidth, storage and compute power on an elastic, on-demand basis, over the Internet. Companies reason for choosing an IaaS environment differ, depending on the size of the organization and the nature of the business. Cost is often the primary reason. For Small and Medium Businesses with a limited capital budget, IaaS shifts the capital requirement to an operational expense that tracks with the growth of the business.
Even among large enterprises, infrastructure costs are a driving force for considering IaaS. IaaS other key benefits include improved cash flow, accommodation of widely inaccurate provision planning, and exceptional transparency in utilization and costs. Tata Communications has demonstrated its commitment to IaaS with the introduction of InstaCompute. Joining our suite of managed services that also includes colocation and managed hosting, Insta Compute adds a key component to the company’s IT services road map.
Virtual private cloud (VPC): An IaaS computing, networking, and storage environment operated by a service provider for a single organization that is a subset of a larger cloud infrastructure (for example, a public cloud). AVPC (also known as a virtual private data centre) is virtually partitioned from the larger cloud, typically through a firewall and VLAN, rather than completely physically separated. VPCs are operated by service providers, and typically come packaged with a set of enterprise data centre services.
The cloud infrastructure services market, and in particular the virtual private cloud (VPC) market, is a compelling opportunity for network and infrastructure service providers. Cloud infrastructure services - also known as Infrastructure as a Service (IaaS) - involve the provisioning of pre-packaged managed infrastructure in the form of virtual server instances. Virtual instances include components of varying size or capacity such as storage, RAM, and CPU processing power, as well as a preferred server operating system (for example, Windows or Linux).
These services allow customer organizations to deploy and manage their own applications on virtualized servers that are hosted offsite at a service provider data center, thus enabling customers to focus on managing their application workloads without needing to maintain the underlying server infrastructure. If cloud computing is to achieve its potential, there needs to be a clear understanding of the various issues involved, both from the perspectives of the providers and the consumers of the technology.
